INDICATING-SIGNAL FOB AUTOMOBILES.

y Speciilcation of Letters Patent. Patented Apr? 19, 1921.

Application led December 17, 1919. Serial No. 345,657. l

To all whom it may concern Be it known that I JOHN D. MULVEHILL, a citizen of the United States, residing at Seattle, in the county of King and State of Washington, haveinvented certain new and useful Improvements in Indicating-Signals for Automobiles, of which the following is a specification.

This invention relates to automobile signals and more particularly to that type of signals which provide combined visual and sounding means for indicating the direction of a turn onwhen a stop is to'be made.

An object of my invention is to provide a manually operated signal which will indicate equally aswell at night as by day, whenever a turn or stop is to be made. 'f Another object is tol provide a suitable signal for an automobile which will be both visual and audible, and also easy to operate` and inexpensive to manufacture.

'Other objects will appear as the description proceeds.

In the accompanying drawings which form a part of my specification.

Figure 1 is a plan view of an automobile with my improved signals in position;

Fig. 2 is a diagram of the wiring of the circuits, and

Fig. 3 is a side elevation, partly broken away, showing the two lamps and their supporting means. -f

Like reference numerals represent like parts throughout the following specification. f v

At each side of the automobile body 1 and near the rear thereof are positioned a pair of supporting brackets or members 2 which support transparent globes 3, which are rel' movably mounted thereon and held in place by suitable means, such as by set screws 4.

A Vpair of sockets 5 are attached to each of said supporting brackets 2, for the re-` ception of red and green bulbs 6 and 7, re-

spectively. The se lamps or bulbs are connected in circuit with a suitable switch 8 and storage battery 9, by means of electric wire or'cable 10. A bell 11 and buzzer 12 are also connected in circuit with the red #bulbs 6, so that when a left turn is' to be made, the red light on the left side of the automobile and the bell 11 will operate.

Likewise, when a right turny is to be made,

the red light on the right side of the automobile, and the buzzer 12 will operate. When a stop is to be made, the switch 8 is thrown to middle point', thus lighting the green bulbs 7. on both sides of the automo bile.F Itwill be seen that lthe signals will indicate equally as well at night as by day, as there are both visual and audible signals.

The switch 8 has a manually operated switch arm 13, which contacts with the points 14, 15 and 16, which indicate a turn to the left, a stop, and a turn to the right, res ectively.

he wiring of the circuits, is such that should a bulb burn out, the bell or buzzer would be rendered inoperative, thereby notifying the driver of the automobile of his trouble.

' Many minor changes in detail of construction may be resorted to without departure from the spirit ofthe invention Having thus described my invention what I claim as new and desire to secure by Letters Patent of the United States is:

A direction signaling indicator comprising a pair of lamp fixtures, one upon each sideiof the vehicle, lamps of two different colors one of'each color .in each fixture and visible from both front and rear of the vehicle, an audible electrically operated signal in series with one of said lamps, an audible electrically operated signal of a nature contrasting with said first mentioned sianal in series with the lampl on the opposite side ofthe vehicle from and `of the same color as the lamp in series with which the first mentioned signal is connected, and a switch for selectively operating leither lamp of similar lcolor with its coperatiiig audible signal to indicate the proposed direction of a' turn or for operating the two lamps of the other color to indicate a proposed s top.

In testimony whereof I aiiix my signature in presence of two witnesses.
